The DJ Project / Discussion / Help: JWebBrowser crashes on Windows 10

Michael Garcia - 2021-10-07

Hi,

Our application has been working fine w/DJNative swing until today. There were security updates applied and we now crash when we create our JWebBrowser. Here's the stacktrace w/some options I saw turned on in other posts.

NativeSwing[2]: Starting peer VM #2

I've seen similar stacks posted but no resolution to the problem. I'm thinking there is a GPO applied by our security team that's causing this but I have no idea what to look for. Does anyone know what Windows settings might be causing this or a way to work around this crash?
Thanks,
-Mike

what do you mean by security updates? windows update or firewall/antivirus? we had problems with node32/eset updates and generated some firewall rules (whiltelist exceptions) on the firewall

Our organization applies security updates that Windows releases and updates some of the tools on our systems. For example they just applied the KB5005573 update from Microsoft and upgraded Firefox to version 78.14.0.

We still can't figure out what's going on. Are there any settings that we can modify that might make this issue go away?

  Hi,
  
  I suspect a network configuration change, or an antivirus that is
  interfering with the internal communication channel. Did you try to turn
  off the antivirus and/or firewall to check if they are the culprit?
  
  Cheers,
  -Christopher
